Lazaridis said he was unable to give a time-frame for the full recovery of the service around the globe. " It is too soon to say that this issue is fully resolved," he added.

On Wednesday, RIM said that email systems were operating, and BlackBerry Messenger was online and traffic was passing successfully. Browsing was however not available in Europe, Middle East, India, Africa, and some parts of Latin America.

The company said late Wednesday that it was seeing a significant increase in service levels In Europe, Middle East, India and Africa. "Service levels are also progressing well in the U.S., Canada and Latin America and we are seeing increased traffic throughput on most services, although there are still some delays and services levels may still vary amongst customers," the company said on its website.

RIM has blamed the outages on a core switch failure within RIMs infrastructure. Although the system is designed to failover to a back-up switch, the failover did not function as previously tested. As a result, a large backlog of data was generated, which the company is now trying to clear.
